(Optional) Enabling the Ping to a Virtual IP Address

(Optional) Enabling the Ping to a Virtual IP Address

Context

The device allows user devices to ping a virtual IP address to serve the following purposes:
  • Monitors the operating status of the master in a VRRP6 group.
  • Monitors communication between a user device and a network connected through a default gateway that uses the virtual IP address.

If the ping to a virtual IP address is enabled, a device on an external network can ping a virtual IP address. This exposes the device to ICMP-based attacks. The undo vrrp virtual-ip ping enable command can be used to disable the ping function.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run vrrp virtual-ip ping enable

    The ping to a virtual IP address is enabled.

    By default, the ping function is enabled. The master in a VRRP group responds to ping packets sent to the virtual IP address.
